摘要： A fuel injection control system for an internal combustion engine can obtain an optimum fuel injection quantity in response to a traveling load without the need for a large memory. The gear position discrimination unit determines the present gear position Ngp on the basis of the vehicle speed Vpls and the engine speed NE. The Kgpd calculation unit calculates the correction factor by gear Kgpd on the basis of the gear position Ngp and the engine speed NE. The state judgment unit judges whether the engine is in a steady state or in a transient state. The map selection unit selects, on the basis of the judgment result of the engine state, the PB map or the TH map for determining the basic injection quantity Ti. The basic injection quantity determination unit determines the basic injection quantity Ti on the basis of a product of the PB map or TH map and the correction factor by gear Kgpd.

摘要： To allow an engine having an intake duct for drawing running air to produce a high output by performing appropriate fuel injection depending on dynamic pressure variations. A vehicle speed corrective coefficient calculator calculates a fuel corrective coefficient KVPLS based on a vehicle speed VPLS, and a throttle corrective coefficient calculator calculates a corrective coefficient KV&thgr;TH based on a throttle opening &thgr;TH. A corrective coefficient multiplier multiplies the fuel corrective coefficient KVPLS and the corrective coefficient KV&thgr;TH, thus calculating a vehicle speed fuel adjustment corrective coefficient KVAF. An injection time calculator calculates a basic injection time TiM based on the throttle opening &thgr;TH and an engine rotational speed Ne, and also calculates a fuel injection time Ti by reading the vehicle speed fuel adjustment corrective coefficient KVAF and correcting the basic injection time TiM. When the engine rotational speed Ne is equal to or higher than a predetermined value Ne1 and also when the transmission is shifted to a low gear position, a corrective coefficient KVAF signal is applied to the injection time calculator.
